It's up to Gamesaudio or anyone else to verify exactly what happened, but after some looking around, John Wesley Harter did in fact die on May 13, 1983 off the Eiffel Tower.
NY Times had a snippet to write for this in 1983
And if you scroll far enough you will find his name in a listing of burials at Oak Grove Cemetary in Delaware, OH.
It's always interesting to research into these kind of things and find as much truth as you can!
